Juventus take on Roma on Saturday evening, looking to maintain their incredible start to the Serie A season.

The Old Lady have won 15 of their 16 league games so far, establishing an eight-point lead over Napoli.

It’s certainly a different story as far as Roma are concerned.

Last season’s Champions League semi-finalists have struggled this campaign and currently sit in seventh after six wins, six draws and four losses.

It’s fair to say Eusebio Di Francesco’s side have been pretty inconsistent.

Will they be able to stop Cristiano Ronaldo from adding to his 11 league goals?

One thing is for sure, the five-time Ballon d’Or winner won’t be lacking in motivation.

Ronaldo has played against Roma on six occasions, scoring five goals.

But perhaps the most enjoyable clash against the Italians came when he was at Manchester United.

The Red Devils had lost their 2007 quarter-final first-leg against Roma 2-1 and needed to overturn that at Old Trafford to progress to the last four.

And they did that in style, winning 7-1 with a 22-year-old Ronaldo bagging a brace.

And the superstar can still remember how the Roma players reacted to his performance that night.

"When it was 6-0, they asked me to stop, an opponent begged me to stop dribbling,” he said, per Calcio Mercato.

“Others threatened to hurt me. Roma? There is no player with whom I would exchange a shirt.”

You can understand Roma players begging for mercy but threatening to hurt him is totally out of order.

No wonder Ronaldo still holds a grudge and will be desperate to get one over Roma once again this weekend.
